Bugs fixed:

  • 35544 - Fix wrong version of NewtonSoft.dll
  • 35987 - Crash when stopping remote iOS run
  • 35993 - Remote profiling on iOS devices not working
  • 36210 - Fix profiling .exe's
  • 35926 - Fix double registration of services
  • 36429 - Stats labels are trimmed
  • 36607 - Can’t profile tvOS template app
  • 36408 - Can’t run a 2nd instance

This is a preview release and there are definite limitations, including but not limited to:

  • No official support for profiling Release builds
  • Data sets are correct at time of collection but data mining and representation is preliminary. This will improve in future releases.
  • Time instrument not available for Android and tvOS profiling
  • Support for Xamarin.Mac app profiling is preliminary
  • Enabling Boehm for iOS builds results in no useful data on devices, as allocations and calls need to be disabled
  • Performance with large apps has been improved, but still lacking some

We encourage users to get in touch and file bug reports so we can continue to make this tool more useful and more stable.
